AdBlue in a diesel car: two tanks, two fillers

No single liquid but two: that's what plenty of newer diesels near Llangadog and Llandyry carry, with diesel feeding the engine. Stored in a tank of its own, AdBlue is sprayed into the exhaust stream to clean it.

There's a filler for each tank. Other cars keep the AdBlue filler in your boot or under the bonnet; a lot of others have the two side by side under one flap. The diesel side is filled at the petrol pump all the time. A driver who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and much less regularly. The error lives in that gap.

AdBlue in the diesel tank around Llangadog: how it takes place

Carelessness seldom causes it. What does is three things lining up at once.

Haste follows from the warning. The vehicle tells you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up happens quickly, before work on a driveway off Meinciau Road, or on the way home in the car park outside Masons Arms.

New-to-you cars come second, too. Hire cars, new vehicles and company cars put their fillers in new places, and the hand goes for the cap used on the old one.

Lastly, the bottle goes in: a diesel filler or AdBlue one, it goes in just as readily, and once the tip starts, nothing halts it. Mynyddygarreg or the middle of Llangadog: it is the same few seconds in both.

The AdBlue filler and the diesel filler: telling them apart

A few seconds is all these take — so run through them before you pour anything, on a driveway in Four Roads or a forecourt in Llangadog.

  • Read the cap instead of going by where it sits: AdBlue ones are commonly blue or marked "AdBlue", and diesel ones normally are not.
  • Plenty of vehicles give AdBlue the smaller filler of the two.
  • The flap. Look inside the fuel flap for a label. Plenty of motors say there which fuel goes where.
  • The handbook. If the filler is not by your diesel cap, it's in your boot or under the bonnet, and the handbook says which.
  • Check with the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Kidwelly.

Keeping AdBlue out of your diesel tank when you top up

On the day the light appears — anywhere it is around Carmarthenshire — a simple routine to follow.

  • Switch off once parked — level ground, engine off, and not rushed by Parc Gwenllian at the roadside.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
  • Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
  • Finish once the tank fills or the bottle is empty; until then, tip slowly using its built-in spout.
  • Shut the cap, and check once more — making sure the diesel cap remained closed the whole time. Only then, start your car.

Spot at stage two or three that it has already gone into the diesel side? Then stop right there. Don't go on to step five.

Put AdBlue in the diesel tank around Llangadog already?

The short order of things, beginning with not starting the motor. The fuel pump runs on many diesels the moment your ignition goes on — and so keep it off. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where your fuel is drawn from — so don't top up with diesel to thin it.

If you are on a forecourt, whether it's the Murco or the Asda, ask the attendants to help push the vehicle away from the petrol pump. Your own driveway around Llangadog is the place it stays.

If the engine has already run, stop as soon as it is safe then switch off. Come off the M4 — under 10 miles out of Llangadog — at the first junction. About how far did it go? Hopping across Llangadog is less work than a trip of under 25 miles towards Swansea, so say.

What occurs when our engineers get there around Llangadog

Wherever the vehicle came to rest, be it outside the local primary school, beside Kidwelly Industrial Museum or at home, our van travels to it. Both the work and our quote rest on three replies — which liquid, which quantity, and if it has run — so our engineers ask. During the phone call itself, you hear our price — before anything else.

Draining that tank comes next, then a thorough flush of the system. Much more than with petrol, it counts here: the crystals build up, certain metals are attacked, and nothing washes away unaided, however long it is left. Filter cleaned or, if it must be, swapped; fresh diesel in; and then a check of the vehicle. Then our engineers start the engine and check it runs smoothly before we go.

With pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which your motor hasn't run need about half an hour once our technicians are there. Nothing upfront; you settle up on the day. Afterwards, a VAT invoice and a report from the engineer are handed to you for the insurer. While we travel, have a look at your insurance documents; plenty carry cover for misfuelling.
